PLEASE HELP. I GIVE BRAINLIEST. The oldest rocks studied by scientists from sources within our solar system are approximately 4.5 billion years old. The oldest rocks found on Earth are approximately 4.3 billion years old. These observations support the conclusion that
Earth formed at more or less the same time as other objects in the solar system.
What evidence would not fit this conclusion and require a revision of the theory?
a. Rocks found on Earth significantly younger than 4.5 billion years old
b. Rocks found on Earth significantly older than 4.5 billion years old
c. Rocks found in other parts of the solar system significantly younger than 4.5 billion years old
d. Rocks found on Earth with compositions significantly different from rocks from other sources

Three archers each fire four arrows at a target. joe’s four arrows hit at points 10 cm above, 10 cm below, 10 cm to the left, and 10 cm to the right of the center of the target. all four of moe’s arrows hit within 1 cm of a point 20 cm from the center, and flo’s four arrows hit within 1 cm of the center. the contest judge says that one of the archers is precise but not accurate, another archer is accurate but not precise, and the third archer is both accurate and precise. which description applies to which archer? explain
